In a recent study comparing the immune cell response to the commensal
Most organisms which colonize are harmless commensals
and are best left alone.
bacteria on lesional skin may possess markedly reduced antimicrobial activity.
2011) have studied spatial activity and behaviour of various commensal
rodents in an open field and arena with factors that may change the behaviour (social composition, shelter and food).
The huge number of resident microorganisms, identified by modern high-throughput sequencing technology, is called commensal
In addition to their effect on the body's immune response, commensal
bacteria enhance skin health by inhibiting pathogen growth.
If we can understand how aging affects our commensal
population--first in the fly and then in humans--our data suggest that we should be able to impact health span and life span quite strongly, because it is the management of the commensal
population that is critical to the health of the organism.
To the Editor: Members of the genus Haemophilus are commensal
bacteria of the upper respiratory tract, and H.
aureus becoming a pathogen rather than a commensal
of the skin.
It incorporates tables, illustrations, clinical cases, and study questions, and introduces microbiology, commensal
and pathogenic microbial flora in humans, and sterilization, disinfection, and antisepsis, as well as the techniques used by microbiologists and immunologists, then covers immunology (updated and reorganized for this edition), including cells and tissues, innate immunity, antigen-specific immunity, antimicrobial immunity, and vaccines, and bacteria, viruses, fungi, and parasites.
Although immune cells in the skin protect against harmful organisms, until now, it has not been known if the millions of naturally occurring commensal
bacteria in the skin - collectively known as the skin microbiota - also have a beneficial role.
Probiotics are defined as nonpathogenic living microorganisms, including some commensal
bacterial flora, which have beneficial effects on host health and disease prevention and/or treatment.
